Billy Graham's grandson Will Graham believes the world is entering the "end times" and that Jesus Christ may well return in his lifetime.
William Franklin Graham IV, known as Will, is in Scotland where he is hosting the North East Scotland Celebration of Hope at Peterhead Academy. The events will be broadcast live via this link.
Graham, speaking to Christian Today, said his aim was to lead people to Jesus while there is still time.
"A lot of people are on edge. I think people feel like something has got to come to a climax," he said, referring to events in the wider world.
"There seems to be an underlying climax that is on the horizon. For me, as a Christian, I believe that that is going to be a massive war, what the Bible calls Armageddon. The end of days.
"If things continue as they are going, something has got to give. I believe a lot of people are nervous about the long-term future."
The world is in relative peace, he said, with no world war taking place. "But yet at the same time there seems to be conflict around and hatred."
He added: "This cannot continue. Something is going to snap. Something is going to break. I believe that could be the start of the end times for us."
Graham added: "I do not know when the Lord is coming back." But he had been reading Scripture. "The things we never thought would take place are now starting to take place. I do believe that Christ will maybe come in my lifetime. I do believe Christ is coming so I want to tell people about Christ while there is still chance."
Graham, aged 41, the oldest son of Franklin Graham, proclaims the Gospel under the banner of the Billy Graham Evangelistic Association of which he is a vice-president.
In the last ten years he has held evangelistic outreaches on six continents around worldwide, always by invitation.
Besides Scotland, his schedule this year takes in Arizona, Australia, Uganda, Norway and Canada.
Graham, who with his wife, Kendra has two daughters and a son, said his purpose in the UK this week is "spiritual", to tell people about Jesus and work with the local churches.
He described how, unlike his father Franklin who came to faith in his 20s, he gave his life to Christ when just a young boy.
"I went to church. My mum and dad were Christians by now. My grandparents were Christians. I just went to church because that was what mum and dad told me to do. I wa about five years old."
When he was five, he graduated from the infants' church to "grown-up church", where there was eucharistic bread and grape juice.
"I thought I love this, I love snacks. But when it came around my parents did not let me partake. I thought this was because they thought I might drop it on the carpet. That afternoon when we got home they came into my room and explained why I could not have it. It was because it is for those who believed in Jesus Christ and have asked Christ to come into their lives and forgive their sins.
"When I was five I knew I was a sinner. So that is what I did. As a child I gave my life to Christ."
He described his faith even now as "child-like".
Graham said he does not understand everything in the Bible, but through faith can see that Jesus is real.
"There is something in all of mankind that knows that there is something bigger than them. That is what the Bible says. God has put eternity in our hearts. We are made for a relationship with God."
